SECTION 8. ALJUSTHEHT
3-1.
Tuning' ol the ..s.ster Generator
Set the TuT;^; control on the front panel to center
and adjust the Coil Li located on center of TONE
BOARD ij.ooi-ji.J3LY so as to make the frequency of A a;
position
generator
s 1760 Hz.
j
8-2. Adjust inent of Vibrato Rate
Adjust the trimpot R59 on the TONE CONTROL BOARD ASSEMBLY
so as to make the frequency of output sine wave of 93rd
terminal on the hoard as 6.8Hz.

8-3- Adjustment of Ensemble Modulator
a) Ensemble Ilouulation date
Adjust the trinnot RI 4 6 so as to make the frequency of
rectangular wave on the terminal of resistor R91 as 12Hz.
b) Adjustment of Output
Set the Sustain Control on the front panel to 10 on scale,
and adjust the trinipot R101 so that the noise may disappear
at the same time when ensemble sounds fade-out after releas¬
ing a finger from the PI key depressed.
